• This is a cold ai mechanism of a pull-type clutch, characterized by having a stove that restricts the movement of the pull-type clutch.
• FIG. 1 is a longitudinal sectional view of a cooling-in mechanism according to the present invention
• FIG. 2 is a partial perspective view.
• Fig. 1 is a flywheel, which is directly connected to the engine's crankshaft (not shown).
• 2 is a clutch disk on the output side, and the center spline / and 3 are spline-fitted to the output shaft (center line 4) which also serves as the input shaft of the following transmission.
• the front face 5 (the left end face in the figure) faces the flywheel 1, and the rear face faces the press plate 7 in the clutch power assembly 6.
• the clutch is connected, it is pressed by the press plate 7 and presses against the flywheel 1.
• the clutch is released, it is released from the flywheel 1. • y.
• the clutch power par 3D 6 is composed of a clutch par 9 fixed to the flywheel 1 and an annular step on the flywheel 1 side of the inner periphery of the clutch par 9.
• a diaphragm spring 11 whose outer peripheral portion is supported via a wire ring 10 fitted in a portion 22 and a flywheel of an outer peripheral annular portion 12 of the diaphragm spring 11
• Preplate plate 7 that supports the inner peripheral edge on the side of File 1 7, and a stop plate 18 that connects between the press plate 7 and the press plate 9
• an annular holder 13 air wheel plate
• the radial width of the outer annular portion 12 of the diaphragm spring 1 1 is L 1, and the fulcrum projection 1 of the wire ring 0 and the platter plate 7 in the width of L 2 therebetween. Supported by 4. Inside the outer annular portion 2, there are a plurality of window holes 15 at equal intervals on the same circumference. A slit 16 extends radially inward, and a release lever portion 17 as shown in FIG. 2 is formed between adjacent slits 16 and 16. .
• the diaphragm frame spring 11 has a spring load P 1 applied from the fulcrum 14 to the pres- sure plate 7 by the outer peripheral annular portion 12.
• the facing 5 is normally pressed against the flywheel 1 and the clutch maintains the connected state.
• To cut the clutch apply a release load P 2 to the end of the release lever 17 by a release bearing (not shown), The part 2 is bent back with the wiring 10 as a fulcrum, and the facing 5 is released.
• One end of the strap plate 18 is fastened to the clutch force par 9 by a rivet ⁇ 9, and the direction of the anti-rotation of the clutch (see FIG. 1)
• the other end is fastened to the outer ridge 21 of the press plate 7 by another rivet 20, and the normal press is performed. A slight effort has been made to move the capture 7 away from the flywheel 1.
• the annular holder 13 newly adopted according to the present invention has a small gap between the surface of the outer annular portion 12 of the diaphragm spring 1 ⁇ on the side opposite to the flywheel 1.
• the strip 23 extends from the inner periphery through the window hole 15 to the flywheel 1 through the window hole 15, and the tip of the leg 23 is bent at a right angle. It is bent and fastened to the inner projection 25 of the y-shape plate 7 by the rivet 24.
• the blade piece 26 extends from the inner peripheral edge of the holder 13 to the center side through an upright portion 26 c rising slightly to the flywheel side.
• a slight gap L 3 is provided between the sections 12. This gap L3 is used when the carriage is to be transported or stored for a long period of time in the state of the clutch force par assembly alone except for the flywheel 1 and the clutch disk 2 from the state shown in Fig. 1. While the ring 11 is deformed to the free state, the toe collar 27 comes into contact with the outer peripheral annular portion 12 to prevent the press plate 7 from swinging. Also, when cutting the clutch in the state shown in FIG. 1, the outer peripheral annular portion 12 comes into contact with the stopper 27 and the press plate 7 is actively pressed.
• the gap L 3 can be made small enough to be separated from the wire 5.
• the clutch cover assembly 6 is mounted on an automobile, etc.
• the annular holder 13 integrated with the rivet 24 comes into direct contact with the air outside the clutch, and has a large relative rotation based on the rotation of the clutch. Because they come into contact with each other at a high speed, the blades 26 and 2 are integrated with the holder 13, so that both serve as cooling fins, and the press plate
• the ripening of 7 is actively released to the atmosphere outside the clutch. Also, since the leg piece 23 passes through the window hole 15, it functions as a detent member of the diaphragm spring 11, and the position of the diaphragm spring 1 is accurate. And no relative sliding occurs at the press-contact portion with the wire ring 10 and the fulcrum projection 14. In addition, when transporting or storing without flywheel and clutch disk, the stopper 27 contacts the outer peripheral annular part 12 to prevent the Restrict the movement of Lele 7 to the side of the flywheel 1.
• the annular holder ⁇ 3 and the blade piece 26 integrated with the holder 13 are integrated with the press plate 7 via the leg piece 23. Since the clutch is in direct contact with the air outside the clutch, a high relative speed can be obtained between the clutch and the external air while the clutch is rotating, and the press 7 can be positively discharged to the outside air, and the cooling effect of the press plate 7 and the facing 5 can be improved.
• the leg 23 connects the holder 13 to the pres- sure plate 7 through the window hole 15 which is unnecessary in the pull type clutch. Dafra
• the mechanism is a rotation stop mechanism for the spring 11, and there is no need to provide a dedicated rotation stop mechanism, which simplifies the structure.
• the blade piece 26 is provided in the window hole portion where the leg piece 23 does not pass, air outside the clutch is positively passed through the window hole 15 and the clutch is closed. It can be press-fitted into the latch, and even in severe operating conditions in which the clutch is frequently turned on and off, the friction surface of the press plate 7 is deformed or the fitting 5 is burned out. The problem that occurs is eliminated.
• the stopper 27 is integrally provided on the outer peripheral edge of the annular holder 13, there is no clutch disk 2 before being attached to the flywheel 1 (the clutch force). make sure the deformation and damage of the strap plate 18 due to the swinging of the y-plate 7 during transportation or storage in a stacked state. By setting the gap L3 small enough, the release lever 17 is operated in the direction of the arrow P2 to release the leg piece 2 3 Through this, the press plate 7 can be positively separated from the flushing 5 and the creep phenomenon can be reliably prevented.
